It actually starts out as the blue asbestos mineral called crocidolite. Like all asbestos minerals, crocidolite typically grows in long, thin fibers. In some geologically bizarre cases, quartz replaces crocidolite and assumes this fibrous structure, in the process often becoming stained by iron to shades that range from golden yellow to brown; we call this material tigereye. When a stone is properly oriented, the fibrous structure left behind by the now-absent crocidolite intensely reflects light to produce tigereye's characteristic chatoyance.

Rhodochrosite is a manganese mineral related to the ubiquitous mineral calcium carbonate, or, calcite. All of these minerals are soft, usually about 3 in hardness, with three strong parting planes or cleavages. This makes cutting gemstones from them a challenge, and setting and protecting them in jewelry mountings even more of a challenge. The color of pure gem rhodochrosite can best be described as a slightly orange pink-red, very close to the color of the meat of a ripe watermelon. World-wide localities of significance include Argentina, where it forms quantities of large stalactitic cave growths of bright pink banded material.

Named from the Greek chrysos - "gold" and kolla - "glue" in allusion to the name of the material used to solder gold. It forms in the altered parts of copper deposits and occurs with azurite, malachite and cuprite and may suggest that copper deposits are nearby. It (obviously) occurs in copper-mining areas, particularly Chile, the former USSR, and Zaire. Pure chrysocolla is soft and fragile and therefore not appropriate for use in jewelry. Occasionally, chrysocolla can have a turquoise color and be used as a fraudulent substitute for the more precious stone. Hardness is variable from 2 to 4.

Is the result of volcanic lava coming in contact with water. Often the lava pours into a lake or ocean and is cooled quickly. This process produces a glassy texture in the resulting rock. Iron and magnesium give the obsidian a dark green to black color. Obsidian can contain small bubbles of air that are aligned along layers created as the molten rock was flowing before being cooled. Inclusions of small, white, radially clustered crystals of cristobalite in the black glass produce a blotchy or snowflake pattern. Hardness is 5 - 5.5 .

From the semiprecious stones, there is one, the strange and remarkable blue stone called LAPIS LAZULI, which was already know before our Era by the Pharaohes. Queen Cleopatra used it as a personal adornment, from the Latin "lapis" - stone - and the Arabic "lazuli" - blue - is a rock composed of various minerals. Its intense blue color is given by the "lazurita." Rarely found chemically pure, this cherished semi-precious stone is opaque and reaches a vitreous shine when is rigorously polished. It is a hard stone, possessing a 5 to 6 hardness on the Mohl scale. Our planet provides only two lapislazuli resources: one in Badakschan, Afganistan, and the other in the Andes Mountains, east of Ovalle, a small town north of Santiago, Chile.

Pietersite was first discovered by Sid Pieters in 1962 while prospecting farm land. He registered the find in the mineral records of Britain, which was published in 1964 naming the material Pietersite. Pietersite is formed from a crocidolite type asbestos or variety of Riebeckite. The process begins with Hawk Eye, the name given to the blue variety of Tiger Eye. This opaque aggregate is formed when quartz replaces the blue/green mineral crocidolite creating iridescent planes or fractures with a silky luster.

a microcrystaline variety of quartz This stone was the favorite jewel or stone of Queen Anne of England and has remained popular all the way through the reign of Queen Victoria. The Greeks and Romans used the stone in cameos. The name comes from the Greek words "Chryso" (golden) and "prason" (a leek) and it was considered the perfect dream stone. In Egypt, the stone was set next to Lapis Lazuli for beads and jewelry. It can be seen today decorating many buildings in beautiful Prague, including the Chapel of St. Wencelas. The well-known designer, Peter Carl Faberge, used it often in his exquisite pieces. The stone is even referenced in the Bible.

Stichtite is formed when the plates of the earth collide. It is a Manganese/Chromium Carbonate-Hydroxyl/Hydride found in South Africa and Australia. It has a hardness of 1.5-2.0 Mohs (which is relatively soft), and is usually found as a deposit on another mineral. For being a soft stone, it really holds together well, takes a high polish and is non-toxic.

Pronounced As: malkit, a mineral, the green basic carbonate of copper occurring in crystals of the monoclinic system or (more usually) in masses. It is translucent or opaque; the luster is silky, vitreous, adamantine, or dull. An important ore of copper, it also serves as a gem and for various ornamental purposes and, when finely ground, as a pigment. It is found associated with other ores of copper) in various parts of the United States and in Chile, Russia, Congo (Kinshasa), Zimbabwe, and Australia.

This shell does not have a light underneath even tho it appears to be glowing from within. It is a very sophisticated type of dichroic film coating ,comprised of precious metals that have been exposed to various levels of electricity, that allows certain wave lengths of light to be relected while opposite wave lengths or light are transmitted. This explains the color changes as the piece is moved in different angles. Displaying these on a dark, like a black, background enhances the reflective characteristics fo this
